📘 Keep a tongue shot from meaning muscle alone

A chameleon tongue launches faster than muscle alone can push. Elastic recoil stores energy; the sticky tip grabs prey. Projection is a catapult, not a simple poke.

What you’ll learn

  1. Elastic launchFrame tongue projection as elastic power amplification.Stored elastic energy recoils to launch the tongue beyond pure muscle push.
  2. Sticky tipSeparate tip adhesion from the launch phase.The tip holds prey after contact; retraction is a different mechanical phase.
  3. Not muscle aloneReject muscle-only explanations for measured projection speeds.Catapult architecture plus a sticky tip explains the shot better than “strong muscle.”
